The targetX attribute determines the positioning in horizontal direction of the convolution matrix relative to a given target pixel in the input image. The leftmost column of the matrix is column number zero. The value must be such that: 0 <= targetX < x of order.

The type attribute is a generic attribute and it has different meaning based on the context in which it's used.

The x2 attribute is used to specify the second x-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the x attribute instead.

JavaScript's strict mode is a way to opt in to a restricted variant of JavaScript, thereby implicitly opting-out of "sloppy mode". Strict mode isn't just a subset: it intentionally has different semantics from normal code. Strict mode code and non-strict mode code can coexist, so scripts can opt into strict mode incrementally.

The JavaScript exception "numbers out of order in {} quantifier" occurs when a quantifier in a regular expression uses the {n,m} syntax but m is less than n.

Public fields are writable, enumerable, and configurable properties defined on each class instance or class constructor.

The version attribute is used to indicate what specification a SVG document conforms to. It is only allowed on the root <svg> element. It is purely advisory and has no influence on rendering or processing.
